I just released an initial version of sas-reader, a Renjin package for reading SAS files (sas7bdat files) into a data.frame.
Sas-reader is available from Maven Central. Add the following dependency to your pom.xml
<dependency>
<groupId>se.alipsa</groupId>
<artifactId>sas-reader</artifactId>
<version>1.0.0</version>
</dependency>
and use it as follows:
library('se.alipsa:sas-reader')
df <- readSas7bdat(paste0(getwd(), "/cattle.sas7bdat"))
